我想做一些国家统计

<?php
$country = mysql_query("SELECT * FROM b_visits WHERE link='$link'");
while($c = mysql_fetch_array($country)){
  $code = $c['c_code'];
  $name = $c['c_name'];

    $broj = mysql_num_rows(mysql_query("SELECT * FROM b_visits WHERE link='$link' AND c_code='$code'"));

  echo "<tr> <td><img style='max-width:20px;max-height:20px;' src='/flags/$code.png'> $name  (<b>$broj</b>) </td> </tr>";   
}  ?>

试试这个：


    <?php
$country = mysql_query("SELECT c_name, count(c_name) as count FROM b_visits WHERE link='$link' group by c_name");
while($c = mysql_fetch_array($country)){
  $broj = $c['count'];
  $name = $c['c_name'];
  echo "<tr> <td><img style='max-width:20px;max-height:20px;' src='/flags/$code.png'> $name  (<b>$broj</b>) </td> </tr>";   
}  ?>
